Description

A kind of anti-jamming gate valve of avoid-dismantle

Technical field

The utility model relates to industrial valve technical field, specifically a kind of anti-jamming gate valve of avoid-dismantle.

Background technique

Gate valve equipment is widely used in the row such as power plant, coal mine, paper mill, coal washery, cement plant, municipal sewage treatment Industry has certain humidity, viscous due to material for the circulation of the media such as raw coal, fine coal, paper pulp, sewage, waste residue to be truncated Degree and specific applying working condition and the method for operation, it is contemplated that the factors such as operating condition, medium of the equipment, to avoid the occurrence of card It puckery, the problems such as material is hardened, and the quick processing after occurring, avoids influencing follow-up equipment operation, skill need to be done to valve body itself Art optimization.

Traditional settling mode:

1, air purge set

In side of valve body and tail portion aperture, gas source is connected, hardened material position easily occurs to valve chamber inside with compressed air It is cleaned, gas forms valve chamber and protects, and to ensure that valve plate switching pathway is unobstructed, but valve body connector is easy blocking, air It can not enter, be unable to reach ideal purging effect；

2, water flow flusher

In valve body two sides and tail portion aperture, water source is connected, according to valve size, valve chamber is rinsed with water, reduces valve chamber inner wall Feed blocking and hardened probability, it is ensured that valve plate switching pathway is unobstructed, but water pipe head is easy blocking, and connector leaked water causes Equipment is got rusty, and the flushing effect of design is also unable to reach；

3, it manually beats

By manually beaing valve body using sledgehammer, hardened material is shaken off, it is not known that bite point exists and beats blind area, Large-scale sledgehammer, which beats, be easy to cause valve body deformation and rupture.

4, valve body is removed

Valve is removed, transport maintenance shop back or is directly disintegrated at is produced from scene, valve chamber tamper material is cleared up, replacement is related close The accessories such as envelope, then return dress, time-consuming and laborious.

Utility model content

The goal of the invention of the utility model is to overcome defect described in background technique, to realize a kind of avoid-dismantle Anti-jamming gate valve, the gate valve can quickly clean the material accumulated in valve chamber, open valve under the premise of not disassembling valve It closes and restores normal, in actual use, the time is greatly saved, saves manpower, reduce maintenance cost.

For achieving the above object, the technical solution of the utility model is: a kind of anti-jamming gate valve of avoid-dismantle, including Valve body, attachment base, valve plate, connecting rod and the handwheel of two sides band connection flange, the valve body and attachment base docking are fixed, the valve Plate is equipped in valve body, and the connecting rod passes through attachment base, and the head end of connecting rod connects by the way that connector and valve plate are fixed Connect, the tail end of the connecting rod is coupled handwheel, in the middle part of the valve body end along the valve plate direction of motion offer it is cylindrical and Through-hole is overhauled in tapped tail portion, is detachably provided with closure bolt in the tail portion maintenance through-hole；The valve body left and right side Side manhole is offered on wall respectively, and is detachably provided with side access panel at the manhole of side；The forward and backward side wall of valve body It is upper to offer main manhole respectively, main access panel is detachably provided at the main manhole.

As the optimal technical scheme of the utility model, the side manhole is correspondingly arranged position in valve body width direction Or position is staggered up and down, side access panel is bolted on the valve body being set to above the manhole of side.

As the optimal technical scheme of the utility model, the main manhole is correspondingly arranged position in the valve plate direction of motion Or position is staggered up and down, main access panel is bolted on the valve body being set to above main manhole.

As the optimal technical scheme of the utility model, sealing ring is provided between the valve body and attachment base, it is described close The sealing clamp with through-hole is additionally provided between seal ring and attachment base, the sealing clamp, which is bolted, is set to the valve Body end portion.

The anti-jamming gate valve of the avoid-dismantle of the utility model the utility model has the advantages that

The anti-jamming gate valve of the avoid-dismantle of the utility model can be applied to the row such as electric power plant coal transportation, dreg removing system, cement plant Industry has certain humidity and viscosity suitable for material, is easy to block under hardened environment inside valve chamber, such as occurs in valve chamber Materials inside is hardened and valve plate bite situation, openable access panel observe stopping state, analyzes bite reason, can be timely Quickly solve the problems, such as that complex working condition lower valve plate bite causes valve damage without general traditional approach, without dismounting Manpower and maintenance time is greatly saved in disintegration valve, can be cleared up by manhole valve chamber, be substantially reduced at the scene Outaged equipment causes economic loss, saves maintenance cost.
